Which nonstandard amino acid residues can openmmforcefields handle?

[HoaSoup]

Hello,

Pardon me for a question for information here, because your repo doesn't have a discussion section. I want to simulate several PDB files containing nonstandard amino acid residues. Which nonstandard amino acid residues can openmmforcefields handle? And where are the forcefield xml files of these residues?

Best regards,
Hoa

OpenFF force fields can handle ~all of them, best with the 3.x line, using either our infrastructure or this package

Hello @mattwthompson ,

Thank you for your suggestion. Due to dependencies with python 3.10, the newest openff-forcefields I can get is 2024.09.0. How to handle the nonstandard amino acid with this version?
